About this game
This reaction time test measures how quickly you can respond to a visual cue. Wait for the screen to turn green, click or tap as fast as you can, and compare your best score in milliseconds. It works on desktop and mobile, so you can test your reflexes with a mouse, trackpad, or touchscreen.
Quick tips
- -Keep your cursor or thumb ready before the color changes.
- -Do not click early; a false start resets the round.
- -Try several attempts and use your best time as the real benchmark.
FAQ
What is a good reaction time?
Many players land between 200ms and 300ms. Scores under 200ms are very quick, especially on a normal browser and device.
Does this reaction test work on mobile?
Yes. You can tap the screen when it turns green, though touch latency can make mobile scores slightly different from desktop scores.
How can I improve my reaction time score?
Stay relaxed, keep your eyes on the cue area, and take short breaks between attempts. Fatigue usually makes reaction times slower.
